【muhakiya】My succubus sister’s food is my semen

In recent years, a phenomenon has begun to occur where girls of a certain age become succubi.
A girl who has been turned into a succubus will have semen as her staple food.
My sister, Mika, is also turned into a succubus, and she wants more of my semen as her brother.

And so Mika spent every day from morning to night, in and out of the house, without a care in the world.

She greedily squeezed my semen out of me.
